Description
[technical field]
The utility model relates to dust catcher, or rather, relates to the dust catcher that a kind of dust collecting structure is simple, dust catching efficiency is high.
[background technology]
Usually, vacuum cleaner is that the suction that utilizes motor to produce is forced to suck air outside, and utilizes filter element to collect the household electrical appliance that the foreign matter that sucks with air comes the clean room internal and external environment.
Simultaneously, the collecting unit of dust of vacuum cleaner has the porous type filter element of foreign matter in the air that the filter mechanism that filters out foreign matter comprises that forced filtration passes through and utilizes the centrifugal force of air whirlwind in flowing to collect the cyclone type collecting unit of dust of foreign matter.At present, be included in the foreign matter disengagement chamber and the foreign matter storage chamber that is used to store the isolated foreign matter of described foreign matter disengagement chamber of separating out foreign objects when forming cyclonic airflow in the cyclone type collecting unit of dust.And described foreign matter disengagement chamber is divided into the first foreign matter storage chamber that is used for the bigger foreign matter of reservoir volume and is used to store the second foreign matter disengagement chamber of tiny dust.By this structure, isolated foreign matter will continue to be deposited in the inside of foreign matter disengagement chamber in the foreign matter disengagement chamber.But the foreign matter of collecting in the foreign matter disengagement chamber can hinder flowing of air when in time not clearing up, thereby has reduced the dust catching efficiency of dust catcher.
[utility model content]
The technical problem that the utility model solves is to overcome the defective that prior art exists, and provides a kind of simple in structure, the dust catcher that dust catching efficiency is high.
The utility model is achieved through the following technical solutions: a kind of dust catcher, comprise main part and collecting unit of dust, described collecting unit of dust comprises the porous type filter, cyclonic separation bucket and foreign matter storage barrel, described cyclonic separation bucket is surrounded by diapire and sidewall and forms, be formed with the air inlet of an air intake passage and connection air intake passage and cyclonic separation bucket at described diapire, described cyclonic separation bucket is round table-like, described air inlet surrounds with the concentric arcuation inwall of the tangent arcuation outer wall of the inside sidewalls of cyclonic separation bucket and a section and described arcuation outer wall by one section and forms, described sidewall upper is provided with a dust mouth, this dust mouth is provided with one and goes out the dirt guide part, this go out the dirt guide part be arcuation and with the tangent setting of cyclonic separation bucket sidewall.
Upper wall that described air intake passage forms for being inclined upwardly by diapire and air channel sidewall surround and form, and the angular range that described upper wall and diapire form is 20 ° ± 7 °.
Described dust mouth is arranged on and is 180 ° position with air inlet in the horizontal direction.
Compared with prior art, the utility model improves by the cyclonic separation bucket being carried out structure, in the bottom of cyclonic separation bucket special air inlet is set, and offer special dedusting mouth at cyclonic separation bucket sidewall, and effectively improved separating effect, simple in structure, dust catching efficiency has the very lifting of great achievement, and in use for some time, can see through the accumulation situation that transparent shell is seen foreign matter storage barrel the inside foreign matter, can clear up foreign matter in time.
